Keeley Neutrino Envelope Filter for trade for another Env Filter. I traded for this pedal a few months ago, it works well, sounds great but its not exactly the type of pedal im looking for. It has many different tonal options and a switch to optimize the pedal for Bass or Guitar, Gain, Peak and a switch (Low | Both | High). Versatile and high quality. I am looking for a more simple Env Filter, on the more conservative side. Looking for trade for a pedal around the same value ($210 from SweetWater). Im in NYC, let me know wacha got.
